Frontotemporal Dementia (FTD):
This is a group of neurodegenerative conditions that affects the frontal and temporal regions of the brain. Other names for FTD are Pick's disease, lobar atrophy, and frontotemporal lobar degeneration. The affected areas of the brain control speech and language, as well as personality and social functioning. Difficulties in language (also called progressive aphasia) and/or social function are the primary symptoms of FTD.
These include corticobasal degeneration (CBD), progressive supranuclear palsy (PSP) and amyotrophic lateral sclerosis (ALS). These conditions involve cognitive difficulties as well as various kinds of motor problems.
